OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS HAIRIPIN Application filed July 25, 1928. Serial No. 295,289.

This invention relates to an improvement in hair pins and particularly in that type of spring-clip hair pins used with bobbed hair. A primary object is to provide a hair pin of simple and cheap construction which will hold its position in the bobbed hair without tendency to work loose. The invention is described in its preferred embodiment in the accompanying drawing, in which Fig. 1 is a view in elevation of a hair pin embodying my invention; Fig. 2 is a vertical view of the inner face of one of the hairclasping members of the hair pin, a portion of the'upper end being shown in section ;;Fig. 3 is a similar view of the inner face of the other hair-clasping member of the hair pin;

Fig. 4 is a view in elevation of a modified form of pin with which my invention may be employed; and Fig. 5 is a similar view of another modified form of hair pin with which my invention may be used.

In the illustration given in Figs. 1, 2 and 3,

1 represents the curved upper or'loop portion of the pin which issubstantially circular in cross section and serves as a spring to retain the legs, or hair-clasping members, 2 and 3 of the pin in close and normally contacting position. Leg 2 is preferably made longer than leg 3 to aid in springing the legs apart. Each of the legs is provided with aflat inner surface 4, the lower portion 5 of which is knurled or superficially roughened. Preferably these roughened surfaces are formed by making transverse grooves across the inner surfaces of the legs.

Types of hair pins commonly employed before my invention have the disadvantage of not remaining securely in position in bobbed hair. They work loose easily, even if pro vided with flat inner faces and with waves or corrugations 6. While the comparatively large corrugations 6 engage entire strands or bundles of hairs, they do not seem to possess a clipping or securing action and, in spite of the pressure exerted soon slip out of place.

' In the operation of my improved pin, individual hairs are caught in the grooves and these serve as wedges to lock entire strands of hair in the pin.

What I regard as new, and desire to secure members having a superficially roughened inner surface adapted to engage individual hairs of the clasped locks.

2. A clip hair pin of the character described, comprising a loop-portion and hairclasping members extendingtherefrom and adapted to lie adjacent each other, said members having their inner surfaces provided with substantially transverse superficial serrations.

3 A clip hair pin of the character described, comprising a loop-portion and hairclasping members extending therefrom and having portions thereof in adjacent relation, said members having superficial roughened inner surfaces and atleast one of said members having a lock-engaging corrugation.

4. A clip hair pin of the character described, comprising a spring loop portion having hair clasping members extending therefrom and having portions thereof in adjacent relation to each other, at least one of said portions in adjacent relation having its inner surface superficially roughened.

5. A clip hair pin of the character described, comprising a spring loop portion and hair clasping members extending therefrom, said members having portions of their inner surfaces substantially in contact, and at leastone of said contacting surfaces being provided with hair-engaging serrations.

6. A clip hair pin of the character described comprising a spring loop portion having hair clasping members extending therefrom. and having portions of their inner surface substantially in contact, at least 95 one of said hair clasping members being provided with a wave, and at least one of said contacting surfaces being substantially roughened.
